I am dissatisfied with the way feats work in D&D. It bugs me that when creating a character one generally must be overly careful or risk 'wasted feats'... I'll skip to the point.
I want characters who make ration decisions about their immediate future. Perhaps feat X will be useless at level 20, but often it can really help get you through level 6 alive. Furthermore, it is terribly annoying to have to take non-wanted prerequisites in order to get the feat you really want.
Feats are not created equally, so doing away with prerequisites would be ugly. Thus I would like to develop/find a point-buy feat system. Instead of the current system, characters would gain a class-dependent number of feat points per level. These can be used at level up to purchase the feats they care about.
I'd leave BAB and Stat prerequisites, just remove the feat tree. Clearly some feats improve directly on others (great cleave) - they would be taken sequentially.
Has anybody experimented with this yet?
